Application filed November 2 4, 1914. Serial No. $713,773,

To all 'whom t may concern:

Be it known that I, WILLIAM F. PAGE, a citizen of the United States,residing at Youngstown, in the county of Mahoning' and State of Ohio,have invented certain new and useful Improvements in Driers; and I dohereby declare the following to be a full, clear, and eXact descriptionyof the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to eXcrement driers, and the primary object ofthe invention is to provide a drier which utilizes heatedgases forremoving the liquid products from 'human excrement and leaving thenitrate proclivities of the eXcrement Vfor forming a commercialfertilizer. i

Another object of this invention is to provide a drier as specifiedwhich `embodies a casing having a plurality of staggeredly disposed panspositioned therein for retaining the excrement, which pans are spacedvertically from each other so as to permit of the passage of heatedgases over the pans for removing the liquid from the excrement and alsoto provide bypasses for Icarrying oli the vaporized liquids orbyproducts of the drying of the eXcrement, and depositing them in asuitable by-product retaining receptacle, which will be subjugated toheated gases for decomposition or vaporization and will pass off withthe gases.

With the foregoing `and other objects in view this invention consists'in such novel features -of construction, @Gmb-mation and arrangement.of parts as will be hereinafter morev fully described,- illustrated in,the accompanying drawings and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like ,characters designate like orcorresponding parts throughout the several views, and in which Figure 1is a vertical sectional view through the nitriary,

Fig. 2 is a fragmentaryside elevation of the nitriary, and l Fig. 3 is afragmentary cross sectional view through the nitriary taken at rightangles to the section illustrated in Fig. 1.

Referring more particularly to the drawings, 1 designates the housing orouter casing of the nitriaryA or eXcrement drier, which is substantiallyrectangular shaped and has its lower end or bottom open and adapted forseating upon a fire boX indicated at 2 in Fig. 2 of the drawings. Thefire boX 2 may be constructed in any suitable manner. The housing 1 ismounted upon the fire box- 2, so as to serve as a flue or stack yforcarrying olf the products of combustion of kand heated gases from avlire built within the fire boX, the purpose of which will behereinafter more fully described.

The housing 1 has -a removable cover 3 mounted upon the uppernendthereof, which has a Vflue or st a'ck 4 formed on the center of the`upper sidethereof yto complete a draft through the housing and firebox.

The housing '1 has a plurality of platforms 5 securedto the sidesthereof and disposed in staggered relation to each other, soj as tocause 'the heated gases rising yfrom the fire boX 2 to travel in atortuous path upwardly through the housing, and travel horizontallyaboveeachand every platform v5, to the end thereof, from whence theytravel vertically until vthey strike thek bottom of the platform abovewhich will deflect the products of combustion and cause them to travelhorizontally across the pans directly beneath the ,platform which theproducts strike.

The platforms 5 are braced intermediate their ends by bracing bars 6which are secured to lthe sides of the housing 1 and eX- tendtransversely therethrough, engaging the under surface of the bottomv ofthe platforms.

-The platforms 5 have their marginal side edges bent upwardly andhorizontally, as is clearly shown'y at y'7 and 8 in Fig. 1 yof thedrawings, so as to form receiving guideways for pans 9. The pans 9 aredetachably or slidably mounted upon the `platforms 5, land they areprovided for retaining the reXcrenient'tolbe acted upon by the productsofl combustion `-passing kupwardly through ,the housing. l

The housing 1 is provided with openings 10 formedin 1,the sides thereof,2and in alinement with the platforms 5, so as to permit of the mountingyof the pans 9 upon the platforms. The openingsrlO are normally closedby doors 11,' which are hingedly cone nected to the housing, as is shownat'1'2, and

which have suitable catch mechanisms 13 se cured to their free ends, forsecurely holding them in closed position.

Pipes 15 and 16 are disposed upon opposite sides of the housing 1, andextend vertically along the sides, being spaced therefrom. The pipe l5has its upper and lower ends bent angularly to the vertical sectionthereof, forming elbows 17 and 18. The elbow 17 is inserted through oneside of the housing 1 and has its open end positioned a short distanceabove the upper surface of the pans 9 which is mounted upon thelowermost of the platforms 5. The upper elbow 18 of the pipe 15 extendsthrough the side of the housing 1 and is positioned a short distanceabove the upper edge of a receptacle 19, which is mounted in the upperend of the housing 1 above the uppermost platforms 5 and a shortdistance inwardly below the inner terminal of the flue 4, as is clearlyshown in Fig. 1 of the drawings. The receptacle 19 has its edges spacedfrom the inner surface of the sides of the housing 1, so as to permitthe heated gases from the furnace or fire box 2 to pass about all sidesof the receptacle for evaporating the by-products and causing them topass out of the casing with the products of combustion.

The pipe 15 has joints 20 formed thereon intermediate of the elbow orangled ends 17 and 18, which joints extend through the sides of thehousing 1 and are positioned above certain of the platforms 5, which aresecured to the sides 21 of the housing 1 along side of which the pipe 15is mounted.

The pipe 16 which is positioned along side the side 22 of the housing 1,or in other words, the side directly opposite to the side 21, has itsends bent angularly for forming elbows 23 and 24. 'Ihe elbow 23 extendsthrough the side 22 and is positioned above the upper surface of thereceptacle 19, similar to the positioning of the elbow 18 of the pipe15. The lower elbow 24 extends through the side 22 and is positionedabove the upper surface of the platform 5 which is next to the lowermostplatform positioned within the housing. The pipe 16 has joints 25 formedthereupon, which extends through the side 22 of the housing and arepositioned above the alternate platforms 5 which are secured to the side22 of the housing.

In treating excrement, preferably human excrement to form a practicalcommercial fertilizer, the excrement in its natural state is placed inthe pans 5 and heated by heated gases passing upwardly in a tortuouspath through the casing, which will vaporize the liquid in theexcrement, leaving a dry deposit in the pan which contains ammonium,phosphorous and potassium compounds in slightly varying quantities,which provides a valuable commercial fertilizer.

The elbows 17 and 24 and the joints 20 and 25 are positioned so that theheated gases will force the greater part of the vaporized by-products ofthe excrement into the pipes 15 and 16, and upwardly through these pipesand outwardly into the top of the casing 1. Any 4parts of theby-products which may be condensed will pass into the pan 19 and berevaporized by the heated gases and pass out of the casing through thestack 4 with the gases for atmospherical distribution.

The heated gases passing over the pans 9 will have a tendency to deposita limited amount.of the carbon carried thereby upon the treatedexcrement which will add to the fertilizing proclivities of the same.

lVhat is claimed is In an excrement drier, the combination, with avfirebox, of a casing mounted upon said iire box, a plurality of pansremovably carried by said casing and disposed in staggered relation toeach other, a top pan positioned centrally within the casing adjacentthe top of the same, an outlet stack carried by the top of-said casing,a pair of pipes supported exteriorly of said casing, transverselyextending pipes connected to said first named pipes and extending intosaid casing, said transversely extending pipes having their innerreceiving ends positioned above said pans, said exteriorly positionedpipes having their upper delivery ends extending into said casing abovesaid top pan for delivering the vaporized liquid product vof theexcrement into the top of the casing for revaporizing any condensed partthereof and for passage out of said stack.

In testimony whereof I aiix my signature in presence of two witnesses.
